    • How do functions work in C language?

    The program comes to a line of code containing a “function call”.

  • The program enters the function (starts at the first line in the function code).
  • All instructions inside of the function are executed from top to bottom.
  • The program leaves the function and goes back to where it started from.

    • How to write functions in C language?

    Writing to a binary file.

  • Example 3: Write to a binary file using fwrite () In this program,we create a new file program.bin in the C drive.
  • Reading from a binary file.
  • Example 4: Read from a binary file using fread () In this program,you read the same file program.bin and loop through the records one by one.
